rMPRovED WATER-SUPPLY REG-Urhsr011;!

F CHICAGO, ILLINOIS.

atea December 22, 186s.

The B'ohedule refened to in these Letters Patent and mak-ing part of thesame.

To all whom itmcy concern:

Be it known that I, GEORGE P.' NUT'rrNG, of Ohiinvented a new andimproved Water-Supply Regulator; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willvenable others skilled in the artfto makeand use the same, referencebeing had tothe accompanying drawf ings, forming part of thisspecification, in which- Figure l is a vertical longitudinal section ofmy invention.

Figure 2 is a horizontal section ofthe same.

Similar letters of reference indicate like parts..

The object of this invention is to maintain the proper water-supply inboilers, by admitting. steam to the supply-pump, when the water reachesa certain level, aud also to announce to the'attendant the fact, thestate of the water-level, when, for any reason, the supply-pump ilailsto maintain the proper level.-

It consists in the arrangement of parts, as will be hereinafter morefully described.

A is a water-chamber, of metal, surmounted by a steam-chamber, B.

The water-chamber is, in practice, connected with the boiler by a pipe,C, located near the bottom of the boiler a little below the line of theproper water-level, to be maintained in the latter by the opening c,through which the rod d passes to operate the steamevalves in thesteam-chamber.

D is a discharge-cock, for the water-chamber. E is a hollow iioat, ofcopper or othersheet-metal,

rlhe iioat is buoyant on the water, and is formed with a .concavity orrecess on its under side, which recess, being filled with water, causesthe float to respond 'l more quickly to the subsidence of the water inobedience to the vacuum induced in the recess by the said subsidence. f

The oat is attached, by a lever, G, to some fixed point within thechamber, as a lug on the steampipc H, which latter leads from thevboiler, and up through the interior of the water-chamber, and terminatesin a valve-chest, I, with the inten'or of which it communi-- cates.

The upper side of t-hisv valve-chamber seats two conical or otherlifting-valves, having their stems attached t o a lever, b, and, atequal distances 4on each 'side of the upright c, affording bearings forthe fulcrum-pin, on which the said lever c vibrates.

The aforesaid rod d connects th lever G. l

` It will be observed that the steam-valves e e are reversed, onevopening downward and the ,other opening upward, and, in practice, theareas of the under side of the valves are equal, that they willbebalanced by the steam-pressure, thereby exerting no considerable elever b with the a pin, h, on the rod d, when the latter is moveddownward by the float when the water subsides to a'certain predeterminedlevel, for which the mechanism was arranged, and in which case, thelever Lbeing. moved, the valve f will be moved from its seat, and theescaping steam will announce to the attendant that the water has reacheda low level.

The whistle may be of anysuitable construction, the commonpocket-whistle form being suiiciently loud for the purpose, `lalthough asteam-whistle of the common form is shown in the drawings. Either maybe'used. M is a spring, actingv in the lever L, to keep the valveseated, 'when the lever L is not actuated by the pin `h, as abovedescribed.

When the water in the boiler begins to subside from the level at whichit is to be maintained, the float will open the valves e, and admitsteam to the chamber B, from which it ows'through the pipe J to thesteampump, and sets .it in motion, thus raising the water'-V .leveL Thisapparatus operates to maintain the water in the'boiler at or near thesame level, for, as the water subsides, the valves are opened, and thepump isldrven faster, to increase the supply, and as the wat-er rises,the valves are correspondingly closed, thus decreasing the velocityofthe pump, and the quantity of water supplied by it to the boiler.

y Thecock D is used to clear out sediment from the. -water-chamber, orto serve as a pet-cock in adjusting the apparatus to a change ofwater-level for it. The cock is wholly or partially opened, to regulatethe discharge withV reference to the induction-cock 0,' so that thewater will pass from the chamber faster than it enters. The result willbe that the valves will be opened.-

Having thus described my invention, I claim Aas new, and desire tosecure by Letter Patent-V The arrangement of the chambers A B, pipes H Jvalve-chest I, valves c e, lever b, rod d, having adjustable pin h,lever G, oat F, arm L,aud whistle K, as

herein set forth and shown.
